’66 is obviously the LOVE colors . . . And in ’66 I had my LOVE show at the Stable Gallery. And 6, I have a big 6 there, and since I have 66 I chose to use the 666 which comes out of my sixth Dream. This could be a part of my sixth Dream. And LOVE is the LOVE show, and I was on the Bowery at that time.
